Perhaps you should try some spelling variations:
yan duong » yan cong, lam duong
duong van » cong van, duong anh
van west » van soest, van het, van es
yang jun » yang jui, pang jun, yang judy
yang jin » yang jie, ying jin, shang jin
hong hai » shang hai, zhong tai, dang hai
yan tin » yuan ting, yang lin
wang » wing, wan

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR lang) yan duong van west ((yan tin) OR (((yang jun) OR (yang jin)))) hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or lang) yan duong van west ((yan tin) or (((yang jun) OR (yang jin)))) hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or lang) yan duong van west ((yan tin) or (((yang jun) OR (yang jin)))) hong hai ;*.
